For open source developers logs of private 1:1 discussions are also highly valuable, so this would only be a bandaid.
The two I regularly encounter (which shared storage fixes) is either moving to a different device (or trying to remember which ones have which bits of history on) and also integrating new team members.
The latter is especially important if you're doing anything technical/support related; if you've had 2 days of discussions and want to add someone else in, they need the history, not for you to try and cherry pick the important bits of the last few hours to then fail to get them upto speed.
